The hominidae form a family of living and fossil forms that somewhat resemble modern human beings, but also resemble monkeys and apes. As research continued, other hominids soon evolved. The species Homo erectus began to migrate to Africa about a million years ago. What counts in this instance is the evidence that Homo erectus was more able, inventive, and adaptable to different environments that many had previously believed they may not be able to adapt to.
This species had a considerably larger brain than it's predecessors, it was considered by some to be the first "real" human, although they were not the same as our present species, Homo sapiens. About 100,000 years ago people of a modern time of Homo sapiens began to appear. Human Skeletons began appearing about 20,000 years ago. Up until that time we did not recognized the people in Africa as what they are, our distant ancestors of our present day population.
The use of stone tools and fire are in the distant background of Africa history. Two other simplifying discoveries bring us to where history discovers agriculture and animal husbandry that made vast new amounts of energy available to many. Human history illustrates people who lived by gathering wild crops, who over time settled down to grow these crops. They changed from gathering to producing food, which was probably a gradual development. Early steps towards agriculture included intensive ways of collecting grains.
This made possible population growth and migration into more settled territory. The language spoken by the migrating grain gatherers were ancestors of the large family of afro-Asiatic languages. Sometime later agricultural technology began to change society especially in Egypt. Egyptian religion can be understood by referring to African religion. Twelve thousand years ago the Sahara was habitable, but dry, people hunted across the territory that was later to become Egypt. Hunting and fishing was done on the Sahara when it went through wet phases. The Sahara later went though a progressive drought that led people to withdraw from the desert in all directions. The people who moved south presumably continued as fishermen and agriculturally developed
